Application filed June 11, 1910. Serial No. 566,351.

To all whom it may concern. Be it known that I, GEORGE L. HALL, a

citizen of thefUnited States, residing in the county, and

specification.

In the drawings: Figure 1 is a side elevation of the clamp, the guard rail and track rail being shown in transverse sectional View; Fig. 2 a plan view of the clamp ap plied to the railsyFig. 3 a side elevation of afportion of a clampshowing a slight variaprovide a guar v rolled T-beam section bent to form a yoke,

tron in the arrangement of the yoke and the clamping wedges, the guard ra1l belng shown in vertical sectional view; Fig. 4 a

plan view of the construction shown in Fig.

3; Flg, 5 a view similar to Fig. 1 showing a slight and diflerent arrangement of the clamping wedges; Fig. 6 a planview of the construction shown in Fig. 5; Fig. a view similar to Fig. 3 showing still another variation in the arran ement of clamping wedges;

Fig. 8 a plan view of the device shown in The main ob'ect of this invention is to rail clamp composed of a and to arrange within the said yoke suitable longitudinally movable clamping means. A further object of the invention is to provide means whereby the clamp wedge or wedges may be moved longitudinally, the wedge moving means being connected to the yoke and to the wedge or wedge Another object of the invention is to simplify the construction of the yoke and thereby cheapen the cost of manufacturing the same, and at the same time form a strong, durable and efficient clamp.

ther objects and advantages of the invention will more fully Referring to the various parts by numerals, 1 designates a yoke formed of a rolled T-beam section, the ends 2 and 2 of the yoke being bent upwardly to receive the clamping wedges and filler or the spacing blocks. In Figs. 1 and 2 both ends of the yoke incline upwardly and inwardly. The yoke is so bent that the" horizontal web 3 of the T-beam forms a support fOIstl'lG track rail 4 and the guard rail 5, and also forms the inner side of the upwardly extending arms of the yoke a ainst which inner side very blocks.

hereinafter appear.

The filler block 6 is arranged between the v of said filler block inclining from its upper downwardly to adapt wardly extending flanges 7 which embrace between them the web 3 of the arm 2*, and thereb hold the filler block a ainstlongitudinal movement. It is manifest that this spacing block must be laced in position on the yo rebefore the yo re is secured in position by means of the clamping wedges.

Between the guard rail and the track rail are arranged the usual spacing blocks 8 and 9 said blocks meetin on a diagonal line, and said meeting edges being ribbed to prevent independentlongitudinal movement of said The block 8 is provided with a hori zontal rib 10 which groove 11 in the block 9 to prevent independent vertical movement of the blocks. The block 8 is formed with depending lugs 12 which engage the edges of the web 3. and prevent longitudinal movement of said block 8. These lugs manifestly prevent longitudinal movement of either of the blocks 8 or 9, the ribbed faces of the blocks locking them together.

rail, the outer surface ts a corresponding The clamp means consist of two wedges 13and 14. The wed which inclines from the upper edge of the block outwardly and downwardly. This the edges of the web 3 of the arm 2 of the yoke. The wedge 13 is formed with an outer surface 17 which inclines from the upper surface of the wedge outwardly and downwardly, to the surface 15 of thewedge 14, and the inner surface of said wedge bears against the web of the guard rail; the upper surface thereof engages under the head of the rail and the lower surface thereof engages the upper surface of the rail base. a

he surfaces 15 and 17are obliqueto the adjoining side of the inwardly and forwardly The wedge 13 is movable longitudinally, and to secure this longitudinal movement said web is formed at its larger endwvith an outwardly extending lug l8, and this lugis ge 14 has a surface 15' to correspond apertured to permit of the passage of a bolt 19. This bolt also passes through the outwardly extending flange 20 of the T-beam, a nut 21 being secured thereon to draw the lug 18 toward the yoke It is manifest that by screwing up the nut 21 the wedge 13 will be moved longitudinally between the stationary wedge 14 and the guard rail, and said longitudinal movement will cause the yoke and all the parts carried thereby to rigidly clamp therails in position. If desired the movable clamping wedge may be driven home by a sledge or other means and the bolt used ,to take up and hold the wedge in position.

In Figs. 3 and t the parts are of the same construction as those shown in Figs. 1 and 2 except that the arm 2* of the yoke is vertical, the flanges 16 of the block 145' being also vertical to accommodate themselves to the vertical arm 2?. The inclined faces 17 and 15 are also vertical. In all other respects the construction of the clamp shown in these figures is the same as that shown in Figs. 1 and 2. By forming the yoke arm 2 vertical the two clamping wedges' may be more readily and more quickly assembled.

In Figs. 5 and 6 the stationary clamping wedge 14. is rigidly secured to the inner side of the vertical arm 2 of the clamping yoke, and the clamping bolt l9 passes through said stationary wedge. The movable wedge 13 is formed with a horizontal part 22 which engages under the rigid wedge block 14* and preventsvertical movement on the said wedge block 1 In the construction shown in Figs. '7 and 8 the wedge blocks 23 and 2e are both movable longitudinally and the clamping bolt 25 extends through the web 20 of the yoke, and also through lugs 26 and 27 on the wedges. By screwing up the nut on said bolt it will be readily seen that both of the wedges will be movable longitudinally. In this construc tion the wedge 23 is formed with a rib 28 which fits a corresponding groove in the wedge 2a whereby independent vertical movement of the wedges will be prevented.

It will thus be seen that I provide a very simple and strong guard rail clamp which may be cheaply manufactured, and which may be easily assembled.

Having thus fully described my invention what I claim asa -new and desire to secure by Letters Patent 355! 1. A guard rail clamp comprising a yoke formed of a T-beam section having its web on the inner side of the yoke, a filler block, a pair of spacingblocks', a pair of clamping wedges one of said wedges being formed with side flanges adapted to engage the web on the inner side of one of the yoke arms, the other wedge being formed with an outwardly extending lug, a bolt. extended through said lug and through the outwardly extending flange of the yoke'arm, the contact faces of said wedges being oblique to the longitudinal axis of the guard rail.

2. A guard rail clamp comprising a yoke formed of a T-beam section the arms of said yoke inclining inwardly and upwardly, the web of the T-beam being on the inner side of the yoke, a. filler block, a pair of spacing blocks, a pair of clamping wedges, one of said wedges'being formed with a side flange to engage the web of one of the yoke arms, the other wedge being formed with an outwardly extended lug at its larger end, and a bolt passing through said lug andthrough the flange of the yoke arm.

3. A guard rail clamp comprising a yoke formed of a T-beam section, a: filler block, a pair of spacing blocks, a pair of clamping wedges, one of said wedges being rigidly secured to the inner side of one of the yoke arms, the other wedge beingarranged between the rigid wedge and the guard rail, and a bolt connecting this latter wedge with the,rigid wedge, and adapted to move said latter wedge longitudinally.

4. A guard rail clamp comprising a yoke,

a filler block, a spacing means, and a pair of clamping wedges, each of said wedges being formed with lugs, and a clamping bolt extending through said lugs and through the yoke and adapted to draw said wedges toward each other, whereby said. wedges will be clamped between the yoke and the guard rail.

5. A guard rail clamp comprising a yoke, a filler block, a spacing means, and a pair of clamping wedges, one of. said wedges being rail and the lower surface thereof engages one of the arms of the yoke to hold said wedge stationary, the other wedge being arranged between the stationary wedge and the'guard rail, and a bolt connecting themovable wedge with the yoke, whereby said wedge may be moved longitudinally.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses this 6th day of June 1910.
